The number of physicians’ offices located inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.

The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.

Full methodology ›The read
Judged by its overall standing, Larkspur, California (ZIP 94939) sits in the top 1.5% healthiest ZIPs nationally (454th) and the top 4.4% of California (75th).
An even profile, with readings pulling both ways: household income registers in the top 1.0% nationally, modeled obesity is in the bottom 1.0% nationally, and physicians lies in the top 1.5% nationally. Modeled utility shutoff registers in the bottom 1.6% nationally, modeled food insecurity is in the bottom 1.6% nationally, and fatal road crashes lies at the national minimum. Modeled transportation registers in the bottom 2.6% nationally, and housing insecurity is in the bottom 2.9% nationally. Dental providers lies in the top 3.4% nationally. Against that, outer-floodplain exposure registers in the top 1.8% nationally.
Placed beside its immediate neighbors, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Put plainly, outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". A healthier nearby ZIP overall is ZIP 94941, just across the boundary. Across other measures, the ZIP also sits on the healthier half of the national range on at least seven of the ten good-life measures tracked here, from quiet and green space to nearby care, a combination reached by about one in twenty-five US ZIP codes.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 1.26 years of 84.5, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match.
